How to Switch Off Ads on My Phone: Android and Samsung Guide

If you're asking how to switch off ads on my phone, the answer depends on where the ads are coming from — browser, apps, notifications, or system settings — and applying the right fix for each. You cannot eliminate every ad entirely, but you can block or significantly reduce most of them using built-in Android and Samsung settings.

What Type of Ads Are Appearing on Your Phone?

Before jumping into settings, it helps to know what you're dealing with. Different ad types need different fixes — and using the wrong one wastes time.

In-app ads inside free apps are served directly by the app developer. There is no setting to turn these off. Your options are upgrading to a paid version or uninstalling the app entirely.

Browser pop-ups and redirects open new tabs or overlay pages while you're browsing.

As noted on Wikipedia's overview of pop-up ads, these are typically generated by JavaScript and browser-level vulnerabilities — which is exactly why the fix lives inside your browser settings, not your phone's general controls.

Notification ads appear in your notification shade — pushed either by an app you've installed or by a website you've given permission to send alerts.

Overlay ads float over your screen even when you're using other apps. These come from apps that have been granted the "Display over other apps" permission.

Lock screen ads show up before you even unlock your phone. On Samsung devices, this is often tied to the customisation service or a third-party launcher.

What's often overlooked is that most people are dealing with more than one of these at the same time — which is why a single settings change rarely solves everything.

Can You Completely Switch Off Ads on Your Phone?

Honestly? No — not entirely.

Ads built into free apps are part of the app's revenue model and cannot be blocked from within Android settings. Personalised ad settings reduce targeting but do not remove ads from appearing. What you can do is block browser pop-ups, stop notification ads, remove overlay permissions, and reduce how much data advertisers use to target you.

In practice, most people find that combining two or three of the steps below removes the majority of disruptive ads.

How to Switch Off Ads on My Phone — Android Settings, Step by Step

Turn Off Ad Personalisation on Your Android Device

This does not stop ads but stops them from being targeted based on your behaviour across apps.

1. Go to Settings > Google > All Services
2. Under Privacy & Security, tap Ads or Ads Privacy
3. Toggle off each of the following:

• Ad topics — stops Android from categorising your interests to share with advertisers
• App-suggested ads — stops apps from sharing data with each other to serve cross-app targeted ads
• Ad measurement — limits data shared to track whether you clicked or acted on an ad

Turn Off Ad Personalisation at Google Account Level

This is separate from the device setting above and affects all devices signed into the same Google account.

1. Open Settings > Google
2. Tap your account name > Google Account
3. Go to Data & Privacy > My Ad Center
4. Toggle off Personalised ads

Both settings work together. Turning off one without the other leaves partial targeting in place.

Block Pop-Up Ads in Your Browser

Google Chrome

1. Open Chrome > tap the three dots (top right) > Settings
2. Go to Site Settings > Pop-ups and redirects
3. Select Don't allow sites to send pop-ups and use redirects
4. Return to Site Settings > tap Ads
5. Set to Block ads on sites that show intrusive or misleading ads

Samsung Internet

1. Open Samsung Internet > tap the three lines > Settings
2. Go to Privacy Dashboard > toggle on Block pop-ups
3. Return to the main menu > tap Ad Blockers to install a content blocker if needed

Firefox

Firefox blocks many pop-ups by default. For stricter control:

1. Tap Menu > Settings > Enhanced Tracking Protection
2. Switch from Standard to Strict mode

Microsoft Edge

1. Open Edge > tap Menu > Settings > Site Settings
2. Go to Site Permissions > Pop-ups and redirects
3. Toggle off Pop-ups and redirects

Stop Notification Ads From Apps

1. Go to Settings > Notifications > App notifications
2. Find the app sending ad notifications
3. Toggle off notifications for that app

Faster shortcut: long-press the notification as it arrives and toggle off notifications directly from the shade.

Stop Notification Ads From Websites (Chrome)

1. Open Chrome and go to the site sending notifications
2. Tap the lock icon (top left) > Permissions
3. Tap Notifications > toggle off Show notifications

Stop Overlay Ads — Remove Display Over Other Apps Permission

1. Go to Settings > Apps
2. Tap Special App Access > Display over other apps
3. Scroll through the list and toggle off any app you did not intentionally grant this permission to

If overlay ads stop after revoking permission for a specific app, consider uninstalling it — it is likely adware.

How to Switch Off Ads on Samsung Galaxy Phones

Samsung adds its own ad layer on top of Android. Both need to be addressed separately.

Turn Off Samsung's Customisation Service

1. Go to Settings > Samsung Account
2. Tap Privacy > Customisation Service
3. Toggle it off

This disables personalised promotions across Samsung apps and, on some models, reduces lock screen ad suggestions. It does not remove ads entirely but stops Samsung from using your data to target them.

Turn Off Lock Screen Ads on Samsung

On some Samsung models, lock screen suggestions appear as ad-style content. To disable:

1. Long-press an empty area of the lock screen
2. Tap Wallpaper Services or Clock style depending on your One UI version
3. Select None to remove content suggestions

Alternatively, go to Settings > Lock Screen > Wallpaper Services and set it to None.

Mute Ad Notifications From Samsung Apps

1. Go to Settings > Notifications > App notifications
2. Find the Samsung app sending promotional alerts
3. Toggle off notifications for that app

How to Find and Remove the App Causing Pop-Up Ads

If pop-ups are still appearing after adjusting browser and notification settings, a specific app is likely responsible.

Check Recently Installed or Updated Apps

Go to Settings > Apps and sort by Last installed or Last updated. If the pop-ups started recently, an app installed around that time is the most likely cause.

Use Safe Mode to Isolate the Problem

1. Press and hold the power button
2. Long-press Power off until the Safe Mode prompt appears
3. Tap Safe Mode to restart

In Safe Mode, only system apps run. If pop-ups stop in Safe Mode, a third-party app is causing them. Restart normally, then uninstall recently added apps one at a time until the problem stops.

Note: Safe Mode only helps diagnose third-party app ads. Browser-based pop-ups will not be affected by this test.

Review App Permissions for Unnecessary Access

Go to Settings > Apps > select a suspicious app > Permissions. Look for apps with access to Phone, Contacts, or SMS that have no obvious reason to need it — a common sign of aggressive adware behaviour.

Run Google Play Protect

1. Open the Play Store > tap your profile picture
2. Go to Play Protect > Scan

According to TechCrunch's report on Google's 2025 Play Store safety findings, Google Play Protect identified more than 27 million malicious apps in 2025 — a significant increase from 13 million in 2024 — with many of these threats specifically targeting users outside the official Play Store. Keeping Play Protect active and scanning regularly is one of the most effective passive defences against adware.

Further Steps If Ads Persist

Use Private DNS to Block Ads at Network Level

Private DNS intercepts your phone's requests to known ad domains and blocks them before they load — across apps and browsers simultaneously.

1. Go to Settings > Network & Internet (or Connections)
2. Tap Private DNS > Private DNS provider hostname
3. Enter a reputable provider such as:

• dns.nextdns.io (NextDNS)
• dns.adguard.com (AdGuard DNS)

4. Tap Save

This is broader than browser-level blocking but is not foolproof. Ads served directly by an app or embedded into a page are not blocked this way. Reputable DNS providers have negligible impact on connection speed.

Clear Your Browser Cache to Fix Redirect Behaviour

Clearing cache does not stop ads directly. It resolves situations where old cached data causes a page to keep redirecting to an ad-heavy version of itself.

Go to Settings > Apps > select your browser > Storage > Clear cache.

Install a Trusted Ad Blocker or Secure Browser

If browser-level pop-ups persist, a dedicated ad blocker extension or a browser with built-in blocking can help. When choosing one, check Play Store ratings, reviews, and the developer name. Be cautious — some apps marketed as ad blockers are themselves adware. Stick to options with a substantial review history and a known developer.

How to Prevent Ad Problems Going Forward

• Install apps only from the Google Play Store
• Keep Google Play Protect active and scanning
• Review app permissions immediately after installing anything new
• Avoid granting notification permissions unless you actively want alerts from that app or site
• Consider paid versions of apps you use every day
• Do not root your Android device — rooting removes built-in protections that limit what apps can access

Conclusion

Switching off ads on your phone comes down to matching the fix to the ad type — browser settings for pop-ups, notification controls for alert-based ads, permission reviews for overlays, and system settings for personalised targeting. No single step eliminates everything, but combining a few of the above handles most of it.

Frequently Asked Questions

Why do pop-up ads keep appearing even after I've blocked them?

Multiple sources can cause ads simultaneously. Blocking browser pop-ups won't stop notification ads or overlay ads. If they persist after all browser and notification settings are adjusted, an adware app is likely still active. Use Safe Mode to identify it.

What is the difference between blocking ads and turning off ad personalisation?

Turning off personalisation reduces how targeted ads are — it does not stop ads from appearing. Blocking (via browser settings, notification controls, or DNS) actively prevents ads from loading or reaching your screen.

Does turning off ad personalisation affect Google or Samsung app functionality?

No. Toggling off ad topics, app-suggested ads, or Samsung's customisation service does not change how the apps work. It only affects how advertisers target you.

Will using Private DNS slow down my phone?

Reputable providers like NextDNS or AdGuard DNS have negligible speed impact in normal use. Some users report slightly faster browsing because ad requests are blocked before loading.

Is it safe to download a third-party ad blocker from the Play Store?

Some are legitimate; some are not. Check the developer name, the number of reviews, and the permissions the app requests. A genuine ad blocker does not need access to your contacts, messages, or call logs.
